Hi,

I notice your budget in the red, have you set own budget or just default?

The saving will be at the end of day, if you didn't have to use daytime boost anymore. And comfort is priceless.

What size is the flat and EPC?

Is 7p per hour accurate seems exceptionally low cost.

OP's off peak rate 21.39p/kWh  I think from 1st Post.

21.39 x 361w/1000=7.7p

The 21.3 KW - so say 19.5 for heating, would suggest the combined 5.5kW charge may have been on for maybe 3 - 3.5  hrs after take away 2kWh for that base snapshot 361x6.5 hrs.

Edit Oops forgot the comment re immersion, so maybe another 2-3kWh less / 40-60p less, just for Quantums.

At 21.39p = £4.17 oops £3.60 (-immersion)  for the day.  Add 42p for base and his SC and immersion get the 5.04 in other pic

And that 7p of course is after the nsh have stopped charging, but possibly running their small fans - 11W×2 and displays 0.5Wx2 - to circulate heat on top of other background load like lights, fridge, alarms, TV etc that may have been on.

It's not the actual cost of the heating, just the spot cost at time of photo.

And confirming they aren't charging all 7 hours etc. And theOP to do the sort of maths above for heat vs total in the £5.04

In earlier photos think they were drawing power, especially as 1st switch on at 4am.


Hopefully the OP can return to normal sleep patterns soon, all these 4am, 5am, 6am etc photos - impressive dedication to learning how these hhr panels work for him and interesting for rest reading.

361W is just a snapshot of the permanent background consumption (standby items) at a moment when nothing is being used 'in anger' apart from the fridge and the freezer.

I'll call Electrician from Monday, considering small living room.
I intend to consider this version, similar to OP though lower heat rating for room.

I thought you were initially looking at a smaller hall unit - not the living room.

https://www.heatershop.co.uk/storage-heaters/dimplex-quantum-rf

This says the 070 is good for 7m2 floor area.  Thats not much more than 2x3 - a box room.

This site quotes even lower area numbers

https://www.electricpoint.com/dimplex-quantum-qm100rf-quantum-storage-heater-1kw-wifi-enabled.html  - at 5 and 11m2 not 7 and 15.

Suspect for a living room - you might be under shooting on the size.  And risking being reliant on peak rate boost.

My living room one is 3.4 kW charge old dumb bricks one. Suspect thats where the OP has the 150 as well.

Dimplex's sizing guide tool - enter room sizes, construction etc and heater type.

For my living room - for 21C room - it said 150 model - at 18 room it said 125 would just do at -3 outside.

As I  replaced Thermostat inc Fan Unit during 2021, old school hall heater continues to work lots of years later, to be replaced after Living Room.
That QM070 700w version is suitable upto 7 m²- certain this is generous for Living Room, though I'll Air Measure to check. 
When Anglian measured windows they are 2mx2m which gives some idea of width, though length to be checked.
